Abstract:
PURPOSE: An electrolytic material including a micro-tube, and an on-off type bio-sensor and a bio-fuel cell using the same are provided to improve the sensitivity and the accuracy of the sensor. CONSTITUTION: A method for manufacturing an electrolytic material includes the following: Enzyme and magnetic nano-particles are mixed with a micro-tube to obtain an enzyme/magnetic nano-particle-micro tube. Salt is added to the mixture of the enzyme/magnetic nano-particle-micro tube to coagulate the enzyme. An amine-bonded bifunctional compound is added to the mixture of the enzyme/magnetic nano-particle-micro tube. The enzyme is cross-linked to integrate the enzyme on the surface of the micro-tube.
